DRAFT-RIGGING FOR, CARS.

SPECIFICATION forming part'of Letters Patent No. 768,611, dated August30, 1904.

Application filed April 18, 1904.

citizen of theUnited State's, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain. new and usefulImprovements in Draft-Riggi mg for Cars;. and I do declare that thefollowing is a full, clear,

and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in draft-riggingfor cars; and theimprovement consists in the constructionand arrangement of parts,substantially as hereinafter shown, and more particularly pointed out inthe claims.

It is my aim to provide a separable draftrigging wherein the parts whichare apt to be+ come broken can be taken apart and repaired and replacedwhile the main parts remain on the car.

In the accompanying drawings, Figure 1 is a side elevation of myimproved draft-rigging mounted upon a section of the draft-timbers orbolsters of the car. Fig. 2 is a bottom View of the draft-rigging shownin Fig, 1. Fig. Sis a perspective view of the spring and bolsterconfining box. Fig.4 illu'strates in perspective view'three distinctfollower-member pieces. Fig. 5 is a perspective View of a section of thelower follower-strap. Fig. 6 is a-longitudinal section on line 9 y, Fig.'7, of my improved draft-rigging with a portion of the car-couplerattached thereto at its front end. Fig. 7 is a section; on lines e2,Fig. 6 looking up; and Fig. 8 is a cross-section on line mm, Fig. 6,.ofmy improved draft-rigging'with the parts assembled as in use. 1 v

The two main members of the draft-rigging comprise side castings A,which are fastened to the timbers B of the car by vertical bolts 2,which pass centrally through said castings, but are exposed at one sideof vertical grooves 3, formed in a central vertical rib t. Thesevertical bolts are subject to great strain and are very often broken andrequire replacing and are also entirely removed in the event of aremoval of the Whole casting A. Ordinarily these bolts are hidden fromview; but in this instance I prefer to use the arrangement Serial No.203,623. No model.)

shown, because in the event of a broken bolt a glance at the open sideof casting A will show the necessity for repairs and also because thesebolts in the course of time accumulate rust and become so wedged inplace that it is a diflicult matter to remove thebolt, whereas fwith'abolt exposed at one'side in a semispherical opening 3 a tap of a'l1ammer upon the bolt will loosen the bolt in its socket and permiteasy removal of the same. Castings A are'preferably constructed with acentral vertical wall Land top and bottom and middle horizontal walls orflanges 5, which extend to. either'side of said vertical wall and whichtogether form a strong support for the other members of thedraft-rigging.

Castings A are connected at their inner side by a box D, which isconfined within a recess 7-in the side of each casting, and crossbolts 8tie said box and casting members together. Ears 9'on the bottom of thebox D overlap and lie flush upon the bottom flange 5 of each member A,and one of the vertical bolts 2 through each member A and said ears isutilized to fasten the box in place.

Box D is provided with guideways 11 upon its top and bottom faces, inwhich followerstraps E and F are adapted to slide. Follower-strap F is astraight bar provided with cross-ribs orprojections 12 at its ends, andstrap E has an upper projecting foot '13, which is bolted to strap F atits inner end by short bolts 14:. The front end of straps F and E engageand are bolted upon the draw-bar coupling member G proper by bolts 15.The pull and push upon the coupler is taken up through the straps andsuitable follower members H and I, which slide in openings 16 in theends of box .D and between which a pair of'heavy coiled springs J areconfined.

In the event of a broken spring or follower member taking place Iprovide a separable construction for conveniently replacing the brokenparts without taking the entire draftrigging apart or removing it fromthe supporting-timbers B, and this construction is comprised in thestraps E and F and an intermediate part K, which is provided withtubular portion 18, free to slide within the I tubular portion offollower H and which part abuts the inner vertical face of foot 13 andis detacbably fastened thereto by a connectingpin or bolt 19. Said bolt19 has a T-shaped head 20 adapted to lock in slots or grooves 21 ateither side of the central slot and at the inner end thereof withintubular portion 18. hen said bolt is in locking position, strap E andpart K are firmly united and move together; but when the strap is to beremoved the nut on bolt 19 is taken ofl, and a quarter-turn is given tosaid bolt to release it from its engagement with grooves 21, and thensaid bolt can be taken out and part K removed from follower- H afterstrap E has been disconnected from strap F. The bottom of box D is nowopen, and new springs or new followers can be replaced therein with easeand convenience. Part K is essential, in that it provides a centralguide for the straps and when pushing upon the coupler forces the strapsinward against the action of the springs. The forward pull upon thecoupler is taken up through both straps, part K, and follower H.

Castings A are provided at their inner end with rearwardly-extendi'ngflanges 25, between which suitable timbers are confined and whichtimbers abut against cross-bolster L. Tie-bolts M connect bolster L withears 26 upon members A.

Box I), straps E and F, the follower, and springs, and all are removabletogether from casting A upon the removal of cross-bolts 8 and the twovertical bolts 2, which-engage ears 9 of box D. This provides aconvenient means for taking the draw-bar and its imme diatedraft-rigging connections bodily from the car.

What I claim is- 1. In draft-riggings, a draft-rigging frame comprisingside members having each a central vertical wall with side flangeslaterally on the outside of said wall, and a series of vertical sidegrooves in the outer face of said wall and tie-bolts in said groovesextending through said flanges, said grooves and bolts disposed atintervals from end to end of said walls, substantially as described.

2. In a draft-rigging, a frame comprising side members, and a centralbox detachably mounted between said side members and secured thereto.follower-straps supported to slide in the top and bottom, respectively,of said box, follower members adapted to slide within the ends of saidbox, a detachable part for one of said straps supported to slide withinone of said follower members, and cushioningsprings between saidmembers, substantially as described.

3. In a draft-rigging for cars, a frame comprising SlClQfllGll'lbQlS anda central connectingbox detachably mounted between said members, andupper and lower follower-strap free to slide upon said box. said lowerstrap having an u iwardly-extending foot and bolts to secure the same tosaid upper strap, follower members to slide within the ends of said box,a cushioning-s 'iring between said members confined in said box and anintermediate part between said lower strap and the follower mem bers anddetachably connected with said strap, substantially as described.

1. In a draft-rigging for cars, the combination of side members and aremovable connecting-box therefor with follower-straps for the drawbarmounted to slideupon said box. follower members slidably mounted withinthe ends of said box, a cushioning-spring within the box between saidmembers, a detachable part for one of said straps adapted to slidewithin one of said followers, and means to rel'novably fasten said partsand straps in place within said follower member, substantially asdescribed.

5. In a draft-rigging for cars, a draft-rigging frame comprising sidemembers, a removable connecting-box between said members,follower-straps mounted to slide upon said box, follower sliding memberswithin said box, a detachable part for said straps provided with atubular portion supported to slide within one of said follower members,a removable locking-bolt for said detachable part, and springs betweensaid members, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.

MICHAEL S. LUCAK.
